Definitions

  • the present invention relates to an inflatable vehicle occupant protection device, and also relates to an inflator structure comprising a source of inflation fluid for inflating the protection device.
  • An inflatable vehicle occupant protection device such as an air bag, is part of an apparatus which further includes a collision sensor and an inflator.
  • a collision sensor senses a vehicle collision having at least a predetermined threshold level of severity
  • the inflator is actuated.
  • the inflator then emits inflation fluid which inflates the air bag into the vehicle occupant compartment to help protect an occupant of the vehicle.
  • An air bag and an inflator are typically assembled together as parts of an air bag module which is separate from the collision sensor.
  • the air bag module is located in the vehicle adjacent to the vehicle occupant compartment.
  • an air bag module may be located on the vehicle steering column or in the vehicle instrument panel.
  • An air bag module may also be located in a side portion of the vehicle, such as a door panel, or in another part of the vehicle, such as the roof, the floor, or a seat.
  • An inflator in an air bag module commonly has an elongated cylindrical shape.
  • An air bag module including such an inflator may also include an elongated, tubular diffuser which contains the inflator.
  • the diffuser typically has a row of radially projecting mounting studs for mounting the air bag module in the vehicle. When the air bag module is assembled and installed in the vehicle, the diffuser and the inflator are contained together within an inlet portion of the air bag.
  • the mounting studs project outward through a corresponding row of apertures in the inlet portion of the air bag.
  • the diffuser directs the inflation fluid to flow from the inlet portion of the air bag to a larger, inflatable body portion of the air bag.
  • the inflation fluid inflates the body portion of the air bag into the vehicle occupant compartment to help protect an occupant of the vehicle.
  • an apparatus comprises an inflator structure with a mounting stud.
  • the apparatus further comprises an inflatable vehicle occupant protection device with a panel structure.
  • the panel structure defines a compartment for the inflator structure, and has a wrapped condition in which it retains the inflator structure in the compartment.
  • the panel structure includes first and second panels.
  • a first aperture formed in the first panel communicates with the compartment.
  • the first panel is fixed to the second panel at a seam located between the first aperture and an end of the first panel.
  • a second aperture extends through the first panel at a location between the seam and the end of the first panel. The first and second apertures are aligned to receive the mounting stud on the inflator structure when the panel structure is in the wrapped condition.
  • the panel structure includes an inlet portion of the protection device, and further includes an inflatable body portion of the protection device.
  • the inlet portion defines the compartment for the inflator structure.
  • the body portion is inflatable into a vehicle occupant compartment.
  • the protection device further has seams that maintain a part of the first panel in a loop-shaped configuration extending completely around the compartment. That part of the first panel has an inflation fluid outlet opening communicating the compartment with the body portion of the protection device.
  • FIG. 1 An apparatus 10 comprising a preferred embodiment of the present invention is shown schematically in Figs. 1 and 2.
  • the apparatus 10 includes a particular type of inflatable vehicle occupant protection device 12 which is commonly referred to as an air bag.
  • the air bag 12 is inflatable from a folded, uninflated condition, as shown in Fig. 1, to an unfolded, inflated condition, as shown in Fig. 2.
  • Other inflatable vehicle occupant protection devices that can be used in accordance with the present invention included inflatable seat belts, inflatable knee bolsters, inflatable head liners, and knee bolsters operated by inflatable air bags.
  • the air bag 12 is part of an air bag module 14.
  • Other parts of the module 14 include an inflator 16 and a diffuser 18.
  • the inflator 16 and the diffuser 18 together define an inflator structure 20 which is located inside the air bag 12.
  • the module 14 is designed for installation in a vehicle at a location adjacent to the vehicle occupant compartment 22. As shown by way of example in Figs. 1 and 2, the module 14 is mounted on an upper frame portion 24 of a vehicle seat 26.
  • the inflator 16 contains a source of inflation fluid for inflating the air bag 12.
  • the inflator 16 may contain an ignitable gas generating material for generating a large volume of inflation gas.
  • the inflator 16 may alternatively contain a stored quantity of pressurized inflation fluid, or a combination of pressurized inflation fluid and ignitable material for heating the inflation fluid.
  • the inflator 16 has a elongated cylindrical shape.
  • An electrical initiator 28 is located at one end of the inflator 16.
  • the diffuser 18 is an elongated, generally tubular part which contains the inflator 16 in a known manner.
  • a plurality of inflation fluid outlet openings 30 extend through the diffuser 18.
  • a plurality of mounting studs 32 project from the diffuser 18. In the preferred embodiment of the present invention shown in the drawings, there are three of the mounting studs 32 in a row extending along the diffuser 18 at a location opposite the outlet openings 30.
  • Each mounting stud 32 is threaded, and receives a corresponding nut 34 for fastening the module 14 to the upper frame portion 24 of the vehicle seat 26.
  • the initiator 28 is connected in a electrical circuit 40 with a power source 42 and a normally open switch 44.
  • the power source 42 is preferably the vehicle battery and/or a capacitor.
  • the switch 44 is part of a sensor 46 which senses a condition indicating the occurrence of a vehicle collision.
  • the sensor 46 senses a condition indicating the occurrence of a side-impact vehicle collision.
  • Such a collision-indicating condition may comprise, for example, sudden transverse vehicle acceleration and/or crushing of a side portion of the vehicle.
  • the collision-indicating condition is at or above a predetermined threshold level, it indicates the occurrence of a collision having a predetermined threshold level of severity.
  • the threshold level of collision severity is a level at which inflation of the air bag 12 is desired to help protect an occupant of the vehicle seat 26.
  • the switch 44 then closes and electric current is directed through the initiator 28 to actuate the inflator 16.
  • the inflator 16 When the inflator 16 is actuated, it emits the inflation fluid into the diffuser 18.
  • the diffuser 18 directs the inflation fluid into the air bag 12 to inflate the air bag 12.
  • the cover portion 50 of the seat 26 may have a tear seam (not shown) so as to rupture in a predetermined configuration.
  • the module 14 may also include a cover (not shown) for enclosing the air bag 12 and the other parts of the module 14 inside the cover portion 50 of the seat 26. Such a module cover also would be ruptured by the force of the fluid pressure acting on the air bag 12.
  • the inflation fluid continues to inflate the air bag 12, it moves the air bag 12 outward from the seat 26 and into the vehicle occupant compartment 22.
  • the air bag 12 is constructed of panels that can be formed of any suitable air bag material, including woven materials and plastic films.
  • the panels of air bag material are interconnected along seams that can be formed by stitches, ultrasonic welds, adhesives, heat-staking, or the like, depending upon the particular material of which the panels are formed.
  • the air bag 12 is constructed of panels that are formed of a woven nylon fabric coated with silicone. Such an air bag material is known in the art.
  • the air bag 12 has an inflatable body 60 and a inlet portion 62.
  • the inflatable body 60 is unfolded and inflated outward from the seat 26, as shown in Fig. 2.
  • the inlet portion 62 defines a compartment 63 which contains the inflator structure 20, and is retained on the seat 26 with the inflator structure 20.
  • both the inflatable body 60 and the inlet portion 62 of the air bag 12 are constructed from a single, continuous piece 64 (Fig. 4) of air bag material.
  • the piece 64 of air bag material has an elongated shape with a pair of opposite end edges 66 and 68.
  • the end edges 66 and 68 are both perpendicular to a longitudinal centerline 69 of the piece 64.
  • the piece 64 also has a transverse centerline 71, and includes a pair of panels 72 and 74 on opposite sides of the transverse centerline 71.
  • the first panel 72 extends fully from the transverse centerline 71 to the first end edge 66.
  • the second panel 74 extends fully from the transverse centerline 71 to the second end edge 68.
  • Each of the two panels 72 and 74 is symmetrical about the longitudinal centerline 69.
  • a body portion 76 of the first panel 72 has a pair of opposite side edges 78 which are alike.
  • An end portion 80 of the first panel 72 extends from the body portion 76 to the first end edge 66, and has a pair of opposite side edges 84 which are alike and which are generally parallel to the longitudinal centerline 69.
  • the side edges 84 define a corresponding pair of opposed tabs 86.
  • the end portion 80 of the first panel 72 further has a plurality of apertures in rows that are parallel to the transverse centerline 71. These include rows of first, second, third, and fourth apertures 88, 90, 92, and 94.
  • the first apertures 88 are arranged in a row adjacent to the first end edge 66.
  • the second apertures 90 are substantially larger than the other apertures 88, 92 and 94, and are arranged in a row which is centered on the tabs 86.
  • the third and fourth apertures 92 and 94 are alike, and are arranged in rows between the tabs 86 and the body portion 76.
  • the second panel 74 also has a body portion 100 and an end portion 102.
  • the body portion 100 of the second panel 74 has a pair of opposite side edges 104 which are alike.
  • a pair of fold lines 106 extend partially across the body portion 100, as indicated in dashed lines in Fig. 4, and define the inner boundaries of a corresponding pair of peripheral corner sections 108 of the body portion 100.
  • the end portion 102 of the second panel 74 extends from the body portion 100 to the second end edge 68, and is substantially shorter than the end portion 80 of the first panel 172.
  • the end portion 102 has a pair of opposite side edges 110 which are alike, and has a row of apertures 112 like the row of first apertures 88 at the opposite end of the first panel 72.
  • the first panel 72 is initially moved pivotally about the transverse centerline 71 in a direction from left to right, as viewed in Fig. 4, so as to place it in a position overlying the second panel 74.
  • the inflatable body 60 (Fig. 5) of the air bag 14 is then formed by fastening the body portions 76 and 100 of the first and second panels 72 and 74 to each other. Specifically, when the piece 64 of air bag material is folded about the transverse centerline 71, the side edges 78 of the body portion 76 are placed against the side edges 104 of the body portion 100.
  • the two body portions 76 and 100 are then fastened to each other at a pair of seams 114 and 116 extending along their adjoining side edges 78 and 104.
  • the seams 114 and 116 also connect the corner sections 108 of the second panel 74 to the tabs 86 on the end portion 80 of the first panel 72. This causes a loop 118 to be formed in the end portion 80 of the first panel 72 between the body portion 76 and the tabs 86.

As best shown in Fig. 6, the end edge 66 of the first panel 72 is placed alongside the end edge 68 of the second panel 74. The apertures 88 near the first end edge 66 are aligned with the apertures 112 near the second end edge 68. A seam 120 (shown schematically) fastens the panels 72 and 74 to each other at a location between the aligned apertures 88 and 112 and the adjacent end edges 66 and 68.
  • the first apertures 90 in the end portion 80 of the first panel 72 are arranged as inflation fluid outlet openings communicating the compartment 63 with the body 60 of the air bag 12.
  • the loop 118 in the end portion 80 is flattened, and is located so as to extend partially around the compartment 63.
  • the flattened loop 118 then comprises an inner layer 124 of the end portion 80, and further comprises an outer layer 126 which overlaps the inner layer 124.
  • the inner layer 124 includes the third apertures 92.
  • the outer layer 126 includes the fourth apertures 94.
  • the third and fourth apertures 92 and 94 are aligned with each other, and communicate with the compartment 63 at a location opposite the location of the first apertures 90.
  • An intermediate part 128 of the end portion 80 includes the first apertures 90, extends partially around the compartment 63 between opposite ends of the flattened loop 118.
  • the end portion 80 of the first panel 72, including both the flattened loop 118 and the intermediate part 128, thus has a loop-shaped configuration extending entirely around the compartment 63.
  • the end portion 80 of the first panel 72 is maintained in its loop-shaped configuration by a set of three seams 130, 132 and 134.
  • the first and second seams 130 and 132 are located on opposite sides of the apertures 90.
  • the third seam 134 closes the compartment 63 at a location between the aligned apertures 92 and 94 and the aligned apertures 88 and 112.
  • the third seam 134 is also located between the tabs 86 and the aligned apertures 88 and 112.
  • the first and second panels 72 and 74 have respective end sections 136 and 138 extending from the seam 134 to the end edges 66 and 68.
  • the air bag 14 is foldable from an unwrapped condition, as shown in Fig. 7, to a wrapped condition, as shown in Fig. 8.
  • an open end 140 (Fig. 5) of the compartment 63 is large enough for the inflator structure 20, including the mounting studs 32, to be moved longitudinally into the compartment 63 through the open end 140.
  • the mounting studs 32 are inserted through the aligned apertures 92 and 94 in the flattened loop 118, as shown in Fig. 7.
  • the layers 124 and 126 of the flattened loop 118 are then folded and tucked inward between the inflator structure 20 and the end portion 102, as shown in Fig. 8.
  • the end sections 136 and 138 of the two panels 72 and 74 are then moved upward and to the left, as viewed in Figs. 7 and 8, so that the mounting studs 32 are received through the aligned apertures 88 and 112 adjacent to the end edges 66 and 68.
  • the inlet portion 62 of the air bag 14 is thus wrapped around the inflator structure 20 such that the compartment 63, and the open end 140, are reduced sufficiently in diameter for the inlet portion 62 to retain the inflator structure 20.
